Re: Best affordable filament?

For 27 dollar I think is quite cheap but at the moment there is only one color (why purple?). I will definitely try it once white is available. Thanks for sharing. Not sure why they went with purple, but they didn't want to have a whole bunch of colors to begin with and risk nobody buying them. If ...

Re: Best affordable filament?

Since PP3DP filament was the best bang-for-the-buck filament I had found for running on my Stratasys, I wonder if Stratasys filament will work well on the Up! printer? A local filament extruder is now offering Sabic MG94 filament, which is the resin that Stratasys sells as P430 and ABS-M30: http://c...

Re: Stratasys Prodigy Plus / Leapfrog Xeed / GRRF PRotos X40

$3000 for a Prodigy Plus is a great buy! That's assuming that the machine is in good working order - there's no need for a maintenance contract if everything is running fine and you can take care of basic stuff like lubricating shafts, making sure belts are tensioned, etc.

Re: Print quality of the new colored ABS?

Interesting. I have a mat black filament, but I haven't tried printing with it yet. Perhaps it will be better than the normal glossy black. Incidentally I have a Stratasys Mojo sample in ivory and their filament is SUPER glossy. Not sure if that is an effect from the bath or how it comes out normal...

Re: Clear ABS in the states

Well, you could use Stratasys ABSi (http://www.fortus.com/~/media/Fortus/Files/PDFs/MS-ABSi-FORTUS.ashx), but I'm sure you won't like the price. I don't know of any other sources, but look around for MABS - that's what 'transparent' ABS is (the addition of methyl methacrylate modifies the refractive...

Re: Bulk Order for filament

The filament is spot on .070 inches which is a tiny bit thicker than PP3DP plastic. I'm running without a filament feeder and the spool is on an A-frame stand. My temperature is set to about 245C which I think is a little low - at high feed rates (.4mm layer thickness), the extruder sometime slips ...

But a 2.8kg spool is not too big for a Stratasys printer, which is what I've been running the filament on.

Would it be possible to order filament in bulk on a large cable reel?

Re: printing small holes

How much increase are people using for accurate hole sizes? I find that the outer dimensions are spot on (+/- 0.2mm) but the holes are always undersized by a fair bit. I've tried adding 10% to the diameters, but it's still not enough. At least I'm using a parametric CAD package, so I can change it ...

What PLA resin are you using? I could not get 4043D to feed through my Stratasys reliably... (but the PP3DP filament I got from you ran like a champ)

Re: ABS is not ABS is not ABS (what printing material to use

Over the past week I've been trying out the PP3DP filament in my Stratasys FDM 1600. I'm really impressed by the material - if I didn't know any better, I'd swear that it was actual Stratasys ABS. I'd love to know just what resin they're using...

Re: ABS is not ABS is not ABS (what printing material to use

Colors shouldn't be a problem once we determine what suitable base resins are. I've been investigating solely uncolored natural ABS resins to begin with in order to minimize the effects of color additives.

Re: New material option

Have Blue's material (SABIC MG47 ABS) seems like it is shiny like MakerGear's but there are so many different types of ABS its hard to say if it is the same. The vast majority of filament sellers (in the US, anyhow) are having Chi Mei PA-747 ABS (an extrusion grade) extruded by New Image or Village...

Re: New material option

I'm glad you got it! I've been running the MG47 on my Stratasys, trying to determine the best settings. Lower temperatures seem to be better (I just finished a run at 240 degrees), but 270 should be fine with a small nozzle.

The Makerbot ABS is Chi Mei Polylac PA-747 extruded by Village Plastics, same as what most domestic ABS suppliers are providing as far as I can tell.

Re: Water solluble support material

I think PLA will be a much better support material - not only is it cheap (Makergear sells it for the same price as their ABS, and has it in 1.75mm), but PVA can be a pain to use, as you have to keep it very dry. Plus, PLA for support has already been proven out: http://ifeelbeta.de/index.php/suppor...
